Using Doctrine Entity

[amenophis]

Hi, I've would to use this Provider with this other one (https://github.com/Amenophis/silex-doctrineorm) i've developped.

So when i use the $this->app['serializer']->serialize($items, 'json'), i got an error on my entities : AnnotationException: [Semantical Error] The annotation "@Entity" in class Scrilex\Entity\Project was never imported. Did you maybe forget to add a "use" statement for this annotation?

Any idea ?

Annotations are references to classes. So when your doc block contains an annotation @Entity it tries to load the Entity class. Since it's not loaded, you should add a use statement for that annotation.

You can refer to the Symfony Documentation on Doctrine Entity mapping for a good example. There you see an example where the ORM Mapping entities are imported using use Doctrine\ORM\Mapping as ORM; and referred to in the docblocks as @ORM\Entity.

This is my code after add annotations Prefix

/* * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") * @ORM\Column(type="integer") * @JMS\Type("integer") */ protected $id;

I got this error while it worked properly before use JMS Serializer :

MappingException: No identifier/primary key specified for Entity "Scrilex\Entity\Project" sub class of "". Every Entity must have an identifier/primary key.

[amenophis]

Sorry, i missed an annotation, but i got this error: MappingException: Class "Scrilex\Entity\Task" sub class of "" is not a valid entity or mapped super class.

<?php

namespace Scrilex\Entity;

use Doctrine\ORM\Mapping as ORM;
use JMS\SerializerBundle\Annotation as JMS;

/**
 * @ORM\Entity(repositoryClass="Scrilex\Entity\TaskRepository")
 * @ORM\Table(name="task")
 */
class Task {

    /**
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     * @ORM\Column(type="integer")
     */
    protected $id;

    /**
     * @ORM\ManyToOne(targetEntity="Project", inversedBy="tasks")
     */
    protected $project;

    /**
     * @ORM\ManyToOne(targetEntity="User", inversedBy="tasks")
     */
    protected $user;

    /**

    protected $pos;

    protected $severity;

     */
    protected $content;

    /**
     * @ORM\OneToMany(targetEntity="Task", mappedBy="task")
     * @ORM\OrderBy({"created_at" = "ASC"})
     */
    protected $histories;

    public function getId() { return $this->id; }
    public function getProject() { return $this->project; }
    public function getUser() { return $this->user; }
    public function getPos() { return $this->pos; }

    public function setContent($content) { $this->content = $content; return $this; }
}

@Amenophis I'm not really sure what is going wrong. What I do know is that these are exceptions caused by incorrect Doctrine mapping. Hence, you best try to get support on the doctrine IRC channel or the doctrine mailing list.

If you push your current code to Github, I'm willing to have a look at it quickly.

[amenophis]

The problem were in my code, now I got this error :

Fatal error: Uncaught exception 'Doctrine\Common\Annotations\AnnotationException' with message '[Semantical Error] The annotation "@JMS\SerializerBundle\Annotation\Type" in property Amenophis\UserAdmin\Entity\User::$id does not exist, or could not be auto-loaded.' in D:\wamp\www\Scrilex\vendor\doctrine\common\lib\Doctrine\Common\Annotations\AnnotationException.php on line 52

What is wrong ?

Have you cleared your cache?

[amenophis]

I removed /cache/serializer content, but the problem is the same ...

[amenophis]

You can get code here : https://github.com/Amenophis/Scrilex

[marijn]

How is your autoloader configured? Have you installed via composer? It seems you are using the right class reference but the autoloader is unable to load the class file.

[marijn]

There is no composer file available in that repository…

[amenophis]

gitignore error ...

It's now OK !

[marijn]

I'm sorry. I took a quick look but couldn't detect any anomalies. My schedule doesn't allow me to assist you further at the moment. Perhaps you can check the Symfony IRC channel on freenode (#symfony).

When I have time to look at it I'll check back with you.

[amenophis]

Thanks for helping me !

[amenophis]

Hi, did you look for my problem ?

Thanks !

[amenophis]

I find a way to make it works !

in app.php

require_once __DIR__ . '/../vendor/autoload.php';

//Add the line below: It Works !
$t = new JMS\SerializerBundle\Annotation\Type(array('value' => 'string'));

$app = new Silex\Application();

Any idea ?

[marijn]

It seems the autoloader is not properly registered. See the doctrine documentation for more info.

[marijn]

I've opened a ticket (#4) to document this better for other users. Sorry for the inconvenience.

[amenophis]

How can i help you with this issue ?

[amenophis]

If i add some code here in the provider,

$app['serializer.metadata.annotation_reader'] = $app->share(function () use ($app) {
    die("here");
    AnnotationRegistry::registerAutoloadNamespace("JMS\SerializerBundle\Annotation", $app['serializer.src_directory']);

    return new AnnotationReader();
});

The execution is not stopped, so the method is not called ...

[marijn]

Is your code requesting the $app['serializer'] service?

[amenophis]

Yes, If i put var_dump($namespace); at the top of registerAutoloadNamespace in AnnotationRegistry class, i just see :

string 'Doctrine\ORM\Mapping' (length=20)

JMS namespace not seems not to be registered ...

[tulanowski]

@Amenophis your problem is caused by using wrong namespace. Use use JMS\Serializer\Annotation as JSM; instead of use JMS\SerializerBundle\Annotation as JSM;

... something has changed between versions.

Hi

I was following example in readme and I had similar problem with 'The annotation xxx in class xxx was never imported'. My solution was to change serializer.src_directory to 'path/to/vendor/jms/serializer-bundle' (notice I have removed '/src' at the end).

Maybe you should fix example in readme?
